SELF LUBRICATING SPINNING RING Filed 00'';- 12. 1927 Patented Feb. 4, 193d UNITEDSTATES PATENT OFFICE .HARVEY E. HERB, OF BUFFALO, NEW YORK, ASSIGNOR TO HERB MANUFACTURING 60., INCL, OF BUFFALQ'NEW YORK, A CORPORATION OF NEW YORK SELF-LUBRICATING SPINNING RING Application filed October 12, 1927. Serial No. 225,667.

This invention relates generally to lubricating means for spinnin machines but more particularly to the lubrication of the rings of such machines on which'the thread guides 6 or travelers are mounted.

The principal object of the invention is the provision of a self-lubricating traverse ring of this character which automatically feeds the lubricant to the bearing surface of the ring in a thin film without liability of flooding and without danger of its lodging on the top surfaceof the ring and soiling or damaging the threads.

Another object is to provide the traverse ring with a built-in lubricating chamber constructed and organized to uniformly distribute the lubricant to the inner curved bearing surface of the ring and at a point below the top surface thereof.

A further object of the invention is to provide the ring with means for introducing the lubricant to its chamber.

In the accompanying drawings :Figure 1 is a fragmentary sectional side view of a spinning machine showing the traverse or guide ring and associated parts. Figure 2 is an enlarged top plan view of the improved traverse ring with the traveler in posltion thereon.v Figure 3 is an enlarged transverse section on line 33, Figure 2. Figure 4 is a fragmentary exaggerated section view similar to Figure 3. Figure 5 is a top plan view of the lower section of the traverse ring.

Figure 6 is a fragmentary exaggerated transverse section of a slightly modified form of the invention.

Similar characters of reference indicate .corresponding parts throughout the several views. I

Referring now to Figure 1 showing a part of a spinning machine of ordinary construe-- tion, 10 indicates the take-.up-spool applied to the revolving spindle 11 driven by the belt 12 engaging the spool-pulley 13. In machines of this character, there is a set of feed rolls for the threads to be twisted and a take-up spool for each vertical row of supply bobbins and traversing the several take-up spools from end to end thereof is a vertically-reciprocating bar 14, each spool extending through a corresponding opening 15 in the bar.

vMounted on the top of the latter and sur-' rounding the companion take-up spool 10 is a traverse ring 16 upon which the bar traveler 17 is adapted to revolve. During the opera-- tion of the machine, the bar traveler assumes a substantially upright position and revolves with and about the take-up spool, the threads passing under the traveler before being wound upon the spool, and the traverse bar being reciprocated so that the threads are un formly wound upon the spool in layers. As .shown in Figures 2 and 3, the traverse ring 16 is removably seated on yieldable brackets 18 rising from a base-ring 19 suitably fastened to the reciprocating bar 14. The inner edge of the base-ring terminates, in an upwardly-facing annular flange 20 which is spaced from the inner edge of the traverse ring to produce an annular channel 21 for receiving the depending legs of the bar traveler. The lower side of the traverse ring is spaced from the top of the base-ring 19 to produce a lateral continuation of the bar traveler receiving channel and such side is slightly flared or beveled upwardly and outwardly, providing a bearing face for the bar traveler.

For the purpose of effectually lubricating the bar traveler, I make the traverse ring l6 of a hollow structure to provide a self-contained lubricant chamber 22, within its ordinary dimensional lines, having a restricted passage 23 at its inner edge or wall for supplying the necessary amount of lubricant to such inner edge and thence to the bar traveler, the lubricant flowing by gravity and aided by centrifugal force to the lower free ends of said traveler which engages thelower bearing face of the traverse ring. In the embodiment of the invention shownin Figures 15 inclusive, the ring is composed of a lower or base section 24 having an annular groove 25 which forms the body of the lubricant chamher, and an upper or cover section 26 which is shaped to extend over the grooved upper side of the base ring and around the outer side wall of the latter, such parts being united -to constitute a unitary structure by a pressed wall of the cover section 26 is preferably turned downwardly to form a flange 27 which produces a smooth, finished surface. The 'inner wall 28 of the grooved ring-section 24 is preferably convexly curved at its inner edge and it slightly overlaps the flange 27 of the cover section in spaced relation to produce the restricted passage 23 for the emission or delivery of the lubricant directly on to the curved faceof said wall 28 and belowthe top' wall of the cover section, as seen clearly in Figure 4. It will be observed in this figure that the top surface of the cover section 26 is slightly inclined downwardly and inwardly and that the lubricant-passage 23 of the ring is below the level of the outer top side of the lubricant chamber 22, resulting in a gravity feed of the lubricant from said chamber through its restricted passage. However, the head pressure on the lubricant is not sufficient to force it freely through the passage 23, due to the adhesion of the lubricant to. the passage-walls, and the lubricant forms in a thin film or fillet at the meeting edges of the ring parts 27, 28. As the traveler revolves about the traverse ring, it picks up sufficient oil to constantly and thoroughly lubricate the lower bearing surface of the ring, the oil flowing down the legs of the traveler and thence outwardly by centrifugal force where it deposits a film of oil on said bearing surface.

In its top side the cover section 26 of the traverse ring has one or more vents 30 which serve not only to eliminate the formation. of

air. pockets inthe lubricant-chamber 22 but also serve as inlets for introducing the lubricant thereto. These vents are preferably formed with rims or collars 31 projecting ,iabove the surface of the ring-cover which act to avoid overflowing of the lubricantchamber. 1 1

As shown in Figures 2, 3 and 4, the brackets 18 rising from the base ring 19 are located outwardly of the periphery of the latter and are provided below their top edges with seats orledges 32 preferably formed by slitting the brackets vertically and-punching the re sulting tongues inwardly; The outer bottom side of the traverse ring engages the top edges of these tongues and by disposing the brackets and their seatsras described, any possibility of. the traveler barflegs striking these parts, as when the same assumes an abnormal tilted position on 5 the fectually eliminated.

In the embodiment of'the invention shown in Figure 6, the self-oiling traverse ring consists of a hollow, body 33 formed and shaped from a single blank of'metal and its structural features are otherwise identical with those shown in Figures'15 inclusive. Aside from its simplicity of construction and efficiency of operation, 'this self-oiling ring. for bar travelers and the like insures traverse ring, is efthe introduction of the lubricant at a ,point directly on the inner bearing mote from the top surface 0 the ring, whereby the lubricant is delivered where required without danger of its spreading onto the top surface of the ring and soiling thethreads being twisted. v
